Error writing a file in Swift Playground

Not sure why I am getting the error here. I created the folder 'Shared Playground Data' in documents as instructed. Does anyone have any insight?

import PlaygroundSupport
import Foundation

var fileName = "Csv.csv"
var csvText = "Date,Task,Time Started,Time Ended\n"
fileName.append(csvText)

let fileUrl = playgroundSharedDataDirectory.appendingPathComponent(fileName)
do {
try fileName.write(to: fileUrl, atomically: true, encoding: .utf8)
} catch {print("error")}

I don't know which Xcode introduced this error, but playgroundSharedDataDirectory directory can't be found by Playgrounds on Xcode 13 beta 2, so instead, do this:

Swift 5 version

let docDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let fileName = "Csv.csv"
let outputFileUrl = docDirectory.appendingPathComponent(fileName)

let csvText = "Date,Task,Time Started,Time Ended\n"

do {
  try csvText.write(to: outputFileUrl, atomically: true, encoding: .utf8)
} catch {
  print (error)
}

Your code makes no sense. Why do you append the column headings to the filename? And why do you write the contents of fileName to fileUrl?

You probably want the following:

let fileName = "Csv.csv"
let csvText = "Date,Task,Time Started,Time Ended\n"

let fileUrl = playgroundSharedDataDirectory.appendingPathComponent(fileName)
do {
    try csvText.write(to: fileUrl, atomically: true, encoding: .utf8)
} catch {
    print(error)
}
